Dear PARI lovers,
I would like to announce the release of pari-2.5.3 (STABLE). The sources
and a basic Windows binary are available from
http://pari.math.u-bordeaux.fr/download.html
This is a BUGFIX release for the stable branch. It fixes all significant problems
that could be fixed in a simple, harmless way. However we strongly encourage
you to upgrade since it fixes a number of cases where PARI was returning an
incorrect result.
Thanks to all those who reported problems, on the mailing lists or through
our Bug Tracking System. ( See http://pari.math.u-bordeaux.fr/Bugs/ ), or
who tested the prelease.
Have fun,
Bill and Karim
